Specification of Letters Patent. P t t 29 191g;

Application filed October 14, 1915. Serial No. 55,799.

To all whom it may concern:

Be it known that I, WiLLIAM H. Voss, a

citizen of the United States, residing at parts on existing 'wringers, and in which the safety handle is located in a conspicnous and easily accessible position.

It another object of the invention to provide a safety attachment of the character' described which cannot get out of order and is simple of construction and-easy I of operation.

sectional view on the line llL-li i. l ig. L is a sectional and detail view ot' the nieeh'a'nisn'i upon one. of standards.

l repriwnts in general the lower half of a wrin rrdesigned to he attaehed to a support by slotted ears and provided with sockets to aeeoouuodale"the hall rare-s for the journals of the lower \vringor roll. Rigidly mounted in the. frame. l are. upright standards 4, one. at either side. 'lhese standards are screw-threaded at their upper ends 5. The upper wringer rolls are carried in armsG and provided with pins 7 which take intoiecesses in the rearwardly extending arms? upon the frame 1, and are further provided with apertures through which the standards project gipwari lljl. Sleeved upon the standards l are coil springs 9 hearing at their lower ends the wringer the .-i

against the arm 6 to createtension between the ringer rolls. A cross bar 10 with en larged ends 11 in which are swiveled thumb-screws 12 connects the upper ends of the standards and may. -be adjusted verti-.

cally by means of the tlui'mb-screws. The ores bar 10 is, according to niyinv'ention, provided with dependingT-fianges 13 adjacent either end, upon which are slidably mounted the blocks 1 which are slotted.

vertically and provided at their upper ends with curved hearing surfaces 15 to take against the bottom of-the eross'pieces 10 and at their bottoms with feet-.16 which en gage with the upper ends of the coil springs 9, the blocks 1% being slotted. asshown, so tnat they may move into a position vertially above the coil springs't) without in-.

torturing withthe standards l. The Cross piece 10 is provided. w th a vertical slot 16 at its renter and with,substantially semieireular webs i7 to "provide a pi'otecting' chamber for the" sii'fety release operating mechanism. Pivotally mounted Liponja bolt 18 and spanning the-weh jifs a-J'Ie\-,er -19.- Pivotally connected to it HPOIT fOPPOSitG- sides of. its pivotal pin are -Iinks-QOwi hich at their outer ends are. formed integrally with the blocks 1%. i

The sleeve 21 surrounds ea-elrstandard 4 in order to render more. easy the operation of the springs and to confine-them against getting too far out ofline with respect to me feet it": of the blocks 14. .This element, hmvewr. eould be dispensed with.

In operation, the cross piece 10 is raised by. means of a thumb-Screw 19 until "the hint-ks H are above the upper ends of the springs J when these springs are expanded. The handle. 19 is then operated from the lilorh's it outwardly andeaiisesthem to assome a position directly hetween the outer ends of the rros-ts bar '10 and the upper ends of the springs ihwvhereupon the thumbserows 12 are operated to force the cross liar ll) downwardly and supply whatever tension may he desired to the. wring'er rolls. in ease of euiergenry, such as a catehing of of the operator between the arr-high: rolls, it will only be neetssary to give the lever 19 a sharp push" to move it from the position shown in dotted lines in Fig. This action will instantly retract hath hhii-l-zs and release the tension upon the wrin er roils. To reset the mechanism the. en. oar it) may he raised and the blocks again moved outwardly, as above described. The large leverage obtained upon the blocks 14 in combination with the wide are described by the points of connection between the links 20 and the lever 19, makes the release both instantaneous and easy. The fact that the thumb screws 12 are permanently swiveled in the cross bar prevents the parts from flying apart when the tension is released. 4

Having now described my invention, I claim: 7

1. In a wringer, a pair of rolls, a pair of standards' operatively associated with the rolls, tension means, comprising coil springs bearingon the'upper roll and mounted upon said standards, a cross piece connecting said Standards at theirupper ends and adapted to be moved downwardly thereon, a pair of blocks slida'bly mounted in said cross piece and adapted to be interposed between cross piece and'the upper end. of said coil springs, and means for sinmltaneously and instantaneously withdrawing said blocks to release the wring-er rolls.

2. ins wrlnger, a pair of standards, a pair of rolls associated therewith, tension means arranged adjacent each standard, a cross piece adjustabl'y mounted upon said standstale and release means on said cross piece and ada ted to beinterposed between the same an the tension means and to be in sta-ntl' released.

n a wri'nger, a frame, a pair of stand.- ai'ds thereon, rolls, tension means associated with said standards, a cross bar connecting a the upp r ends of said standards and vertieally adgus'able on said standards, and instantaneously releasable means interposed between said cross bar and said tension means.

4. In a wringer, a pair of standards, a cross piece adjustably connected thereto, blocks having recesses for the accommodation of said standards and slidably mounted on said cross bar, a lever centrally mounted on said cross bar and connections from said lever to said blocks for longitudinally mo"- ing them.

5. In a wringer, a pair of standards screwthreaded at their upper ends, a cross bar having thumb nuts swiveled thereon at either end and in engagement with Said threads, :1 wringer release device mounted on said cross bar and comprisinginstantaneously releasable means interposed between A the same and the ringer rolls.

(5. in apparatus of the class described, rolls, tension means associated therewith, a pair of standards, a cross bar connecting said standards, an enlarged chamber located substantially centrally of said cross bar, tension release means, and a control for said tension release means, comprising a lever pivoted in said chamber and links pivotally connected to said lever at points a substantial distance upon opposite sides of the pivotal point of said lever.

in witness whereof, I hereunto subscribe my name to this specification in the presence of two witnesses.
